Title: Improvements in or relating to speed control of internal combustion engines
IPC: G05D13/00
Filed: 1931-02-13
Abstract: 363,217. Fuel injection pumps. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, PAULIN, G. H. and HORNER, F. H., Willans Works, Rugby. Feb. 1-3, 1931, No. 4565. [Class 102 (i).] In a system for the remote control of the setting of a centrifugal governor controlling the speed of an internalcombustion engine, the governor 1 is loaded by a plurality of loading springs. Two springs 8, 9 engage at one end pistons 20, 24 arranged in cylinders 21, 25. The governor actuates, through a rack 7, the by-pass valve 19 of a fuel injection pump and controls delivery. The pump. plunger 12 is actuated by an eccentric 13 and the bye-pass valve 19 by eccentric 15. Pilot valve 33, 34 actuated by switches control fluid pressure to the cylinders 21, 25. For idle running the spring 8 is compressed by a stop 28, for an intermediate speed, fluid pressure is admitted to the cylinder 21 and the spring 8 is further compressed, and for high speed, fluid pressure is also admitted to the cylinder 25 and the spring 9 is compressed. At each predetermined setting of the governor, there is also a setting of the time of fuel injection, being accom. plished by varying the mean position of the valve 19. When fluid pressure is admitted to cylinder 21, pressure is simultaneously admitted to cylinder 42, raising piston 43 a distance determined by the stop 47, rotating the eccentric shaft 46 against spring bias. Similarly fluid pressure is simultaneously admitted to cylinders 25 and 49 and the time of injection further advanced. To close down the engine, pilot valve 35 actuated by the switches admits fluid pressure to cylinder 30 and actuates rack 7 against the governor loading and sets the valve 19 to by-pass all the fuel.

Title: Improvements in and relating to the moulding of articles from synthetic resins
IPC: B29C35/02
Filed: 1939-02-11
Abstract: 527,906. Moulding articles from synthetic resins. EBONESTOS INDUSTRIES, Ltd., and AMIGO, A. Feb. 11, 1939, No. 4578. [Class 87 (ii)] In the moulding of articles from a packet of laminations or felted fibrous material impregnated with synthetic resins,. one portion of the article to be moulded is first shaped by subjecting the packet while stationary to heat and pressure until only the surface of the portion has hardened sufficiently to lose its stickiness, whereupon the packet is fed forward and another portion of the article is similarly shaped and hardened on the surface while stationary, the whole of the first portion being subjected to at least one further heat and pressure treatment to complete its hardening and the consecutive portions being subjected to the same shaping and hardening treatment in a stationary position until the whole article has been shaped and hardened. The adjacent portions which are consecutively treated may have their marginal zones overlapping one another, the pressure applied to such marginalzones being less than that applied to the remainder of the portions. The consecutive treatment may take place with respect to successive portions of the packet in the longitudinal and/or transverse directions of the packet. In moulding ring- shaped articles wherein the beginning and end of the packet are stepped to fit on to one another when the ring is formed the ring is completed by the two stepped ends being brought together and a final pressure applied thereto. Use may be made of a press comprising two pressure moulds having a free space between them which is open all round so that the packet can be fed both longitudinally and transversely, the marginal zones of the moulds being so shaped that at these parts the free space is increased and the pressure applied to the packet consequently reduced. In the moulding of tubular or hollow articles use may be made of mandrels for forming the cavities. As shown in Fig. 6, the laminated packet 3 lies between a mandrel 11 and moulds 1, 2, and after one pressure application the mandrel is withdrawn in the direction 12 and the packet is fed forward in the direction 13, whereupon the mandrel is also shifted in the direction 13 and pressure again applied. By placing transverse mandrels next to one another and leading laminations of the packet between the mandrels and the moulds, as well as between the individual mandrels, hollow plate-like bodies can be produced. Specification 501,649 is referred to.

Title: Improvements in luminescent screens
IPC: H05B33/12
Filed: 1957-02-11
Abstract: 807,690. Photo-electric devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 11, 1957 [Feb. 14, 1956], No. 4591/57. Class 37. [Also in Group XL (a)] A luminescent screen comprises associated elements 4, 6, Fig. 1, containing an electroluminescent material and a photo-sensitive material respectively and two electrodes 2, 7, combshaped as shown, one electrode being associated with each material, the projections of these electrodes on a surface parallel to the screen constituting interlaced line patterns which do not intersect. In Fig. 1, the elements 4, 6 are separate continuous layers, the thickness of the photo-sensitive layer 6 being less than that of the electroluminescent layer 4 and the spacing between the edges of adjacent parts of the two electrodes in the projection being larger than the combined thickness of the layers 4, 6. In the embodiment shown in Figs. 3 and 4 the screen is built up of locally parallel tracks, spirally arranged, presenting alternately a photo-sensitive track 31 and an electroluminescent track 32, these tracks being provided with electrodes 33, less than the width of the photosensitive track and electrodes 34 associated with the other tracks 32. Auxiliary electrode elements 35 on the same side of the track 31 as the electrodes 33 cover marginally a portion of that track and part of the electroluminescent track 32. The auxiliary electrodes 35 may have high conductivity in which case they are constituted by small relatively insulated surfaces, the dimension of each of which in the track direction is not larger than that transverse thereto or they may be of a material whose conductivity increases with increasing voltage and in this case are continuous. Several other arrangements are described in any of which the electrodes may be comb-shaped, zig-zag or concentric spirals, provided that they follow non-intersecting lines. It is stated that the construction permits a high ratio between the impedance of the non-irradiated photo-sensitive element and that of the associated electroluminescent element without the former element being so thick as to absorb too much of the primary incident radiation. The photo-sensitive material may be cadmium sulphide activated with copper or gallium and the electroluminescent material zinc sulphide activated by copper or aluminium.
